The supply-tank J thereto, and is specie-ally designed to show is connected with a storage-tank, 'K, which the relative positions of my apparatus to the latter contains the petroleum-supply. l'nrnecei Fig 2 is a central vertical section The supply-pipe G and burner E are cont ol the furnace, taken through one of nected by a, coupling, g. Below this coupling,

its blast-pipe and through pipe G is provided with c stop-cock, T which trolcum burners wilh its sup i may he an ordinary plug-valve with an aperletlng valves, 3 is a lure of any suitable form. This plug is pro- J of o e of the petroleum snpvided with a lever, ,which is made to swing cool: and mechanism in front of on arc-dial, O, the latter being snrliow, Fig. marked with a graduated scale. By means of of tnycrc this lever and arc-dial the amount of petro- Fin. 1?. learn admitted through the burner may be ac:

' curntcl y regulated or determined.

A ball-valve, P, is placed within the feed- 0 pipejust above the stop-cock, and as the head of oil allows the pet:- lcuin to flow up to a, stated pressure within the furnace this halt valve automatically checks all (low in excess of this pressure.

The part which I have denominated the burner (marked E in the drawings) consists of a pipe which is cylindrical in form up to the point where it enters the tuyere, and at this point the form of the pipe changes from {00 the cylindrical into the oval. The burner termimics in a. mouth or orifices, N. The cast iihc burner ings which form the wells of the mouth or snilnhlc Gl ilCLIi ol' the burner may he cored out, and

melt ingl'urith n mam through these chambers thus formed the water flows from the lower to the upper compartment, thus cooling the burner and the walls of the orifices. It is evident that the shape or form of the burner and its orifices may be considerabl y varied without affecting the results sought to be accomplished by them. All that is necessary to be observed in the construction of these burners, as Well as of theirsurrounding water-jackets, is that the construction be such as to permit a regular flow and avoid the possibility of melting. I have described but one burner; but it will of course be uudcrstood that each tuyere has its burner, and each burner receives its petroleunrsupply from the circular main 11' through pipes similar to pipes G.

I contemplate locating the storage and feed tanks at such a distance from the furnace that all danger of firc and explosion of the petro I leum will be avoided. The orifices and supplypipes should of course be surrounded with water-jackets, so as to avoid danger from fire. The petroleum is caused to flow through the orifices of the burner by its own weight, and can be held above the point where the burners enter the tuyercs, As already stated, this level is maintained by the use of a float, and this float is so arranged as to operate a valve in the pipe leading from the storage to the feed tanlc In order to maintain a uniform level of the petroleum through the stop-cock L, the retardation of the lieu of liquid caused by the friction in the service-pipes should be compensated for by making said pipes of in creased diameter according to their length.

By means of the above apparatus a predetermined quantity of petroleum may be sup plied to the blast in each 01' the tnyores.

have described my apparatusparticularly as used in connection with blasti'urnaces; but it will 01" course be understood that it is equally applicable to any other kind of furnaces in which petroleum or other liquid fuel is used,- l'or by regulating the flow of the pc troleum, as above described, complete burning may be obtained and the heat-giving power of the petroleum fully utilized.

I claim-- 1. The combination, with the tuyere of a blast or other furnace, of petroleum tanks or reservoirs having floats to maintain a level or head of oil, service-pipes having devices whereby the flow of the petroleum may be regulated,supply-pipes having valves or other substantially as described. 2. The combination, with the tuycre of a blast or other furnace, of petroleum tanks or reservoirs having floats to maintain a level or I head of oil, service -pipes having devices 1 whereby the flow of petroleum may be regui I I lated, supply-pipes having valves or other" regulating dcvices for feeding the petroleum with the blast, protecting Water-jackets, and

safety-valves tor preventingexplosions, substantially as described.

Mi. The combination, with the tuyere ol a blast or other furnace, of petroleum tanks or reservoirs having lloats to maintain a level or head of oil, service-pipes I, having stopcock Q, supply-pipe E, having valve L, lever M, and arc-dial O, a burner, protecting water- ;jacket F, and ball-valve I, substantially as described.
